I think we all agree that when we make a purchase, we want to invest our money well. Therefore, whether you have already bought a great thermal glass or if you are about to do so, we tell you what the care of thermal glasses.

Thermos flasks open

A quality double wall thermal glass does not really need much care. The important thing to enjoy simple maintenance is to choose the best quality model and that best suits your needs.
Cleaning is one of the points that most worries, especially who has to scrub. Well, do not worry because a thermos of beer, a glass of thermal wine, a thermal glass of tea, a jug or a glass of thermal juice of quality will always be able to be washed in the dishwasher.

In mind that these are made of glass or plastic so, as with conventional vessels, we can machine wash.
But if this is not the case, washing them by hand is a simple task and without loss. Dishwasher with neutral pH, warm water and rub! You will see that it is not at all difficult for your thermal beer jug ​​to be unpolluted. It is not necessary to use any extra products or strange ideas.
Of course, if you abuse the dishwasher, it is possible that your double wall thermal glass will lose some transparency. So is the rest of your dinnerware. This is due to the accumulation of small scratches caused by the mechanism of the dishwasher or by the accumulation of lime.
To give it back its natural shine try rubbing it with white vinegar or toothpaste (such as car headlights before you take it to the ITV).
Another more “professional” solution will be to put the whole set of thermal glasses in the dishwasher, without any metal tray or grid or other elements containing metal and include crystals of citric acid to start a program of washing at 60 °, Of course, a complete rinse program that will leave your thermal glass as new, ready to use for years.
Lastly, and in the case of thermal glass vessels, any crystal wax will leave it perfect after a good rub.
Watch, yes, that your double-wall thermal beer glass can be put in the freezer. Thus, you will enjoy the golden drink at an irresistible temperature and for hours.
The same goes for the microwave. Although it is not the common thing, it is not necessary, it is not enough to take into account the purchase of a glass of thermal tea to, if it is the case, put it to microwave heating.
In both cases, care is as simple as not putting them in the freezer or the microwave if they are not suitable for it.

Thermos flasks closed

Finally, and although we are not so much, we also want to comment that the maintenance of closed cups and thermal jars is somewhat more laborious.
Obviously having a lid and with materials such as rubber, washing this product is more difficult. Of course, it is not an impossible task, but as it is understood, it is more difficult than washing an open thermal vessel.
The gum must be fully extended to be cleaned, but, bacteria and moisture will be stored in their insides. Also, being deeper, it costs more to introduce the hand to scrub.
Like the previous ones, the majority of models allow to enter the dishwasher, although it is very important to make sure of this before buying them if we do not usually wash by hand.
The same will happen with the microwave. Although you should not need to use it, a closed glass cup may not be suitable for microwaves, such as stainless steel. Be very careful with this because you can lose your appliance.
